Claims.

The invention relates to store front constructions employing metal strips or bars for the reception of the glass. It has for its principal object the provision of an improved simplified structure wherein the setting may be accomplished from the front side of the window, and wherein any requirement for the use of screws in connection with the clamping members and cover plate therefor is avoided, thus materially reducing the time and labor incident to installation or disassemblingfor replacement purposes, and improving the appearance of the structure. A further object is the provision of improved means for supporting the bottom edge of the glass plate at graduated elevations and in a very secure. manner. such means being particularly adapted for use in the screwless clamping and cover plate construction to which the invention is primarily directed, as above set forth. Certain embodiments of the invention are illustrated in the accompanying drawings, wherein:

Figure l is a section through the construction with the parts in assembled relation, wherein the dotted lines show the position of the clamping spring before it is snapped into holding position. Fig.2 is a view similar to that of Fig. 1 of a modification, but with the dotted lines showing the position of the cover plate before it is snapped into I final position. Fig. 3 is a partial front view of the construction with the cover plate removed to show the location of the clamping springs and setting blocks. Figs. 4 and 5 are detail views of a modified form of setting block which is adjustable as to height, Fig. 4 being a front elevation, and Fig. 5 a section on the line V--V of Fig. 4. And Fig. 6 is a section through a modified form of sash bar.

' Referring to the drawings, 1 is the sash frame of the usual wood construction, 8 is the glass plate forming the window, and 9 is a metal sash bar secured in the sash by means of sets of screws it? and H. The sash bar comprises the back strip l2 and the base strip 13 lying beneath the edge of the glass sheet. The back strip has at its upper edge a gutter E i and a flange l5 bearing against the rear face of the glass sheet. The flange is formed by bending the edge of the back strip, so as to form the recess 56 for receiving one end of the locking spring later described.

The base strip is provided with an upstanding rib i! extending longitudinally thereof in line with the edge of the glass sheet and has its extreme outer end bent away from the sash I, as indicated at it, to provide between such end and the sash i, an outwardly opening slot to receive the flange l9 at the lower edge of the cover strip 20, such strip being of bent or extruded metal. The cover strip is recurved at its upper edge to provide the flange 2| in opposition to the flange l 5 on the back strip and to provide a recess 22 for 5 the locking spring.

The flanges l 5 and 2! are pressed yieldingly to- Ward each other to grip the glass and hold the cover strip in position, by means of a series of springs of V-cross section each comprising the base 23 seated against the rib I1 and the arms 24 and 25 which have their upper ends bent, as shown in Fig. l, and seated in the recesses l6 and 22 respectively. These springs are preferably about four inches in length and are placed at spaced intervals along the base strip it. They are positioned against movement longitudinally of the strip by the heads of the screws H, the distance between a pair of screw heads equaling the length of the spring, as indicated in Fig. 3.

The springs are necessarily applied before the application of the cover strip 26. To position the spring, it is applied as indicated in the dotted lines in Fig. 1, and the base 23 is then pushed inward till it seats against the rib ET. This brings the upper end of the arm 25 against the front face of the glass sheet exerting some pressure thereon, while the upper end of the arm 24 fits into the recess H5. The cover plate 20 is now applied by positioning it as indicated in dotted lines in Fig. 2. A downward movement of the cover strip now forces its flange 2i between the end of the arm 25 and the front face of the glass plate. This brings the bottom flange i9 of the cover strip opposite the slot between the flange it and the sash, and the lower end of the cover strip can now be shoved to the right so that it snaps into such slot, thus completing the assembling operation. The arms 24 and 25 are now sprung apart so that their upper ends exert a substantial degree of pressure on the flanges l5 and 2!, thus clamping the edge of the glass sheet and holding the cover strip yieldingly in the position shown.

The weight of the glass plate is taken by the metal setting blocks 26 provided on their upper sides with leather pads 21 and having their bases slotted so as to receive the rib i? which thus serves to positively position the blocks in alinement with the edge of the glass plate. In order to permit of the drainage of any water which collects in the space 28 back of the rib ll, such rib is flattened out or cut away at intervals as indicated at 29,

29 in Fig. 3. The flanges l8 and IQ of the base and cover strips may also be slotted at intervals to facilitate drainage.

Figs. 4 and 5 illustrate a modified form of setting block which is adjustable as to height. The base portion, of the block is formed in two similar sections 29 and 39 and secured together by the bolt 3! provided with the nut 32, a slot being provided at the line of division for the reception of the rib. The base portion is provided with a socket for receiving the lower end of the top member 33 of the block which carries a leather pad 34 for engagement with the glass plate. The lower part of the top member which fits into the socket in the base portion, is stepped, as illustrated, having three portions 35, 3'6 and 3i of increasing width from the bottom of the series up. This gives three adjustments as to height. By loosening the bolt 32 and separating the parts 29 and 3B, the top member may be lowered so that the portion 31 engages the socket, or the top portion may be adjusted upward one step so that the portion 35 engages the socket.

Fig. 6 illustrates a modified form of sash bar 38, in which the rib' ll of the Fig. 1 construction is omittedand its place taken by the shoulder 38 which acts as the abutment for engaging the base 23 of the V-shaped spring. This shoulder also serves to position the setting blocks it whose bases are formed to fit the shoulder, as illustrated. In this construction, there is no obstacle preventing drainage from the space M to the front side of the cavity beneath the glass plate. The construction and functioning of the parts is, in other respects, the same as described in connection with Figs. 1, 2 and 3, no screws being required except those used for holding the sash bar to the sash frame.
